Correction of postoperative temporal hollowing using a combination of thread-lift and autologous fat graft: a case report

Postoperative temporal hollowing is a complication that can occur after craniectomy or cranioplasty. It is caused by the disinsertion or displacement of the temporalis muscle and atrophy of the superficial temporal fat pad. We introduce a case of temporal hollowing correction using polydioxanone thread-lifting and fat grafts. A 28-year-old man presented with right temporal hollowing and asymmetric bulging of the zygomatic region. The patient wanted an aesthetically favorable correction with a short recovery period, without using a permanent implant. We performed a two-stage procedure. In the first stage, 21 mL of centrifuged fat was obtained, of which 7 mL was injected into the temporal region. A month later, another 4 mL of the stored fat was injected, and thread-lifting was performed through the temporal region after identifying the deep temporal fascia. Four threads were inserted, pulled toward the entry point, and tied. The anchoring of the thread-lifted tissue remained stable, and the volume of grafted fat was well preserved at the 4-month follow-up. The patient was satisfied with the cosmetic results. In this case, temporal hollowing was effectively managed with fat grafting and thread lifting. We recommend this method as an option for reconstruction of temporal hollowing with a short recovery period and high patient satisfaction.
